to him, and that it is in his collection. The identity of this 

 specimen was confirmed by the Editor. 



The claim of the species to be considered British rests upon 

 these captures. The inference that they had been introduced 

 in an earlier stage among plants is contradicted in a great 

 measure by the fact of the simultaneous appearance of the 

 species, in 1859, in the Channel Islands, and in plenty in the 

 North of France, which points clearly to an extensive migra- 

 tion of the species northward. It is difficult to suppose, how- 

 ever, that the isolated specimens captured more than twenty 

 years later were the descendants of such immigrants in this 

 country, and it is far more likely that in each case they were 

 migrants. As in thecase of birds, however, it is difficult to 

 exclude from our fauna, species which voluntarily come to us. 



By the kindness of the Rev. A. Fuller of Chichester, I have 

 been able to examine the original specimen, which had passed 

 from Mr. Mc Arthur's hands into the possession of Mr. Thorn- 

 croft of Brighton, and was purchased by Mr. Fuller at the 

 sale of I\Ir. Thorncroft's collection eighteen years ago. It 

 was evidently a good, well-marked specimen when captured, 

 but lias at some time been damaged. The original label of 

 capture is still attached. The white stripe upon its hind 

 wings is rather broader than usual in the species, the mark- 

 ings of the under side generally are beautifully clear, and the 

 spots at the anal angle brilliant. 



Mr. A. H. Clarke tells me that in Spain, where he has 

 observed this species in plenty, it has rather a strong flight, 

 four or five feet from the ground, and seems to settle on leaves 

 rather than on flowers. 



Lieutenant G. F. Mathew says that in Turkey it is common 

 wherever wild vetches grow, several generations emerging 

 in the year ; and that he found it on the wing even from 

 November to January. 



It is abundant in the South of Europe, over a large portion 

 of Asia, and the whole of Africa, and is frequently sent to me 

 by my friends in Cape Colony.
